Pepe Le Gangster is an animal villain in The Busy World of Richard Scarry. He has a gang of rats called "The Dirty Rats." He doesn't treat his rats at all well, such as often forbidding them to eat, and never allowing them to get clean (when they do he resorts to such moves as dumping trash on them).

Couscous disguises himself as any person when Pepe Le Gangster and his dirty rats see who it is (often when Couscous disguises himself as a woman, Pepe has a tendency to fall in love, so women may be a weakness). Whenever they're captured, Couscous undisguises himself.

He loves eating spaghetti.
